Quinn died after he was shot in front of the Sports Café in the 4300 block of Downman Road. He apparently had been in an argument when bullets were fired at him. Investigators soon developed Martin as a suspect.

On Dec. 2, NOPD Detective Michael McCleery spoke with someone who claimed to have heard but not seen the shooting while stepping off the bus. McCleery later retrieved surveillance footage and realized no bus had been captured on the video, an affidavit filed in court said.

McCleery confronted the witness with that information, and the person admitted to seeing the shooting, the affidavit alleges. The witness reviewed a photographic line-up and identified Martin as the man who killed Quinn, police said.

Tyron Quinn, 28, with his wife, Kiara, and their family.

McCleery on Wednesday obtained a warrant to arrest Martin. Police apprehended him Thursday on Lawrence Road and booked him with one count of second-degree murder.

Martin's initial bail was set at $300,000. In 2009, he pleaded guilty in Orleans Parish Criminal District Court to possession of marijuana as a first-time offender and received six months of probation, records show.

However, he did not pay his required fines and fees, and the court issued a warrant for his arrest. The last minute entry in the record on that case, from 2009, indicated that Martin remained at large.

Quinn, of Algiers, worked for Coca-Cola. He was married and had four children, according to his obituary.
